Title: High load combustor
Inventor: INDOU MASAHIRO
IPC: F23M5/00
Filed: 1981-11-17
Abstract: PURPOSE:To contrive reduction of pressure loss for secondary air supply, by a method wherein a high load combustor part is constituted by casting a heat exchanger pipe in aluminum material whose thermal conductivity is favorable and holding a flame hole, a secondary air jet and fin part for heat exchange between heat exchanger pipes. CONSTITUTION:As mixed gas reacts at a high temperature within a hatched area, a temperature of a flame hole 10 and a secondary air hole 11 becomes high, but if a device is a water boiler, the temperature can be reduced to a low temperature 50-100 deg.C as the temperature of the flame hole 10 and the secondary air hole 11 is close upon that of a material to be heated flowing within a heat exchanger pipe 9 as they are constituted of aluminum material having favorable thermal conductivity and the heat exchanger pipe 9 is built-in the vicinity of the flame hole 10 and the secondry air hole 11 in a body. With this, a fan can be miniaturized as the temperature is lowered and a pressure loss is reduced.

Title: Musical sound signal generating device
Inventor: SHIMIZU MASAHIRO
IPC: G06F17/10
Filed: 1993-06-29
Abstract: PURPOSE:To generate a waveform signal in a complicated shape which repeatedly increases and decreases by determining an applied function by a function arithmetic means on the basis of a data value circulated in a circulation path and making the applied function different. CONSTITUTION:The function arithmetic means is equipped with functions f1 and f2; and the function f1 increases in waveform output value and the function f2 decreases. Then it is checked whether or not the value of the waveform signal exceeds a specific 1st threshold value when a waveform signal which increases is outputted by circulating data in the circulation path by using the function f1. When the value of the waveform signal exceeds the 1st threshold value, the function arithmetic means switches the applied function from f1 to f2. Consequently, the data are circulated in the circulation path of the function f2 and the signal decreases. Further, it is checked whether or not the value of the signal becomes less than a 2nd threshold value, and when so, the function is switched from f2 to f1, thereby outputting the signal waveform which repeatedly increases and decreases.
